Intelligent and online area monitoring system and implementation method thereof

Abstract

The invention discloses an intelligent and online area monitoring system and an implementation method thereof. The system comprises a master distribution automation station, a plurality of intelligent area monitoring substations connected with the master distribution automation station, servers connected with the intelligent area monitoring substations, a plurality of communication terminals capable of realizing information transmission with the servers through wireless communication networks as well as an intelligent and online area monitoring terminal connected with the communication terminals, wherein the intelligent and online area monitoring terminal is connected into electric wires and monitors a whole grid. The system can provide timely and reliable operation data for management automation and power utilization standardization of electric power sectors and can monitor states such as undervoltage, overvoltage, overcurrents, overloads, open circuits / short circuits and the like of distribution areas and users in real time, so that abnormal power utilization behaviors of the users as well as fault states of the areas and all circuits can be discovered timely, the power supply quality is improved, the service level of the electric power sectors is increased, and the safe operation of a power supply system is guaranteed.

Description

technical field [0001] The invention relates to an intelligent on-line monitoring system for a station area and a realization method thereof, which can realize remote monitoring of intelligent general protection, centralized reading and reactive power compensation devices by a power distribution automation master station of each monitoring terminal. Background technique [0002] Rural power grid is an important part of my country's power grid. For a long time, my country's rural low-voltage power grid has a weak grid structure and has been in disrepair for a long time. There have been frequent accidents such as downed poles and disconnected wires, and burning of distribution transformers. . The current construction of a new socialist countryside has put forward higher requirements for rural power grids. To build a safe, economical and reliable rural power grid to provide uninterrupted high-quality power for the vast number of rural users, this requires us to carry out agricu...
